10,20,30 and 40 treating process (step S10-S40) are carried out with preset time gap periods ground.

Tire pressure monitors that unit 50 monitors processing according to the ground execution program loop tire pressure shown in Figure 3 that is installed in the memory device 55.

That is, tire pressure monitors that the control unit 54 of unit 50 determines whether to receive each signal (step S110) with predetermined frequency band.

When determining not receive the signal with predetermined frequency band, when promptly being defined as ' deny ' in step S110, then tire pressure monitors that the control unit 54 of unit 50 stops these processes of execution, returns step S110.

On the other hand, when receive by antenna 52 and acceptor circuit 51 at least one send to control unit 54 have the signal of predetermined frequency band the time, this control unit 54 has determined to receive at least one signal with this predetermined frequency band, promptly step S110 is defined as ' being '.

Subsequently, control unit 54 determines whether to have deposited check ID one of at least (step S120) in memory device 55, and when determining in this memory device 55, not deposit check ID, promptly among the step S120 be defined as ' denying ' time, this control unit 54 forwards later step S150 to.

When determining to check one of ID to be deposited with in this memory device 55 at least, be that being defined as among the step S120 is when ' being ', control unit 54 from memory device 55 read this check ID one of at least have this check ID one of at least (step S121) so that determine to be included in whether checking out one of at least of this detector ID of this received signal in one of at least.

Do not have this check ID one of at least the time when definite this detector ID checks out one of at least, promptly among the step S121 be defined as ' denying ' time, control unit 54 forwards later step S150 to.

When checking out one of at least, definite this detector ID has this check ID one of at least the time, promptly among this step S121 be defined as ' being ' time, 54 of control units determine to be included in the predetermined alarm conditions (step S130) whether this received signal this detected air pressure in one of at least satisfies one of at least each tire.Should predetermined alarm conditions comprise a preset air pressure alarm scope that for example requires to produce alarm.

When the air pressure of the detection of determining is one of at least not in this predetermined alarm scope, control unit 54 determines that not satisfying one of at least of these detected air pressure should predetermined alarm conditions, in other words, the definite result among the step S130 is ' denying ', and then control unit 54 forwards step S150 subsequently to.

On the other hand, when this detected air pressure one of at least is within this predetermined alarm scope the time, these detected air pressure of determining control unit 54 satisfy one of at least should predetermined alarm conditions, in other words, definite result among the step S130 is ' being ', so that this control unit 54 is provided with data, make indicating member 81 indications one warn (step S140), so this indicating member 81 is according to alarm of data indication of this setting.

On the other hand, one of at least do not check out and have check ID one of at least when determining to be included in this detector ID of this received signal in one of at least, be definite result among the step S121 when ' denying ', this control unit 54 determine to be included in this detected air pressure in this received signal whether be not more than one of at least with first embodiment in sign deposit the standard atmosphere (step S150) of cooresponding this 101kPa of condition.

The detected air pressure that comprises in determining this received signal is during one of at least greater than the standard atmosphere of 101kPa, and when promptly the definite result among the step S150 be ' deny ', these control unit 54 these treating processs of termination execution were so that return treatment step S110.

When at least one detected air pressure in being included in this at least one received signal is not more than the standard atmosphere of 101kPa, definite result of step S150 is ' being ', and control unit 54 determines whether the number of detector ID temporary in this memory device 55 is zero (step S160).

When the number of determining detector ID temporary in this memory device 55 was not zero, when promptly the definite result among the step S160 was ' denying ', control unit 54 forwarded later step S180 to.

When determining to be temporarily stored in detector ID number in this memory device 55 and be zero, be that definite result among the step S160 is when ' being ', control unit 54 is deposited the count value C1 reset-to-zero (zero second) of timer TM1 to this, begins one and increases progressively counting (step S170) so that this deposits timer TM1.

Subsequently, control unit 54 determines that whether this count value C1 that deposits timer TM1 is less than 60 seconds (step S180).

In determining that this count value C1 that deposits timer TM1 was less than 60 seconds situation, be that definite result among the step S180 is when ' being ', then this control unit 54 is kept in the detector ID (step S190) that is included in the received signal in memory device 55, and determines whether that this temporary detector ID number becomes 4 (step S200).

When the quantity of determining temporary detector ID became 4, when promptly the definite result among the step S200 was for ' being ', control unit 54 formally was deposited with (step S210) in the memory device 55 to temporary detector ID as check ID.

On the other hand, when the quantity of determining temporary detector ID did not become 4, when promptly the definite result among the step S200 was ' denying ', control unit 54 stopped carrying out this processing and returns treatment step S110.

In addition, when definite this count value C1 that deposits timer TM1 is not less than 60 seconds, when promptly the definite result among the step S180 is ' denying ', the detector ID (step S220) that these control unit 54 cancellations are kept in memory device 55.

Subsequently, with the processing and the operation that are used for depositing the detector ID of

pressure test device

10,20,30 and 40 described according to first embodiment at this memory device 55.

At first, the valve open of tire T1, T2, T3 and T4 makes whole four tire T1, T2, T3 and T4 be deflated.That is, the venting of whole four tire T1, T2, T3 and T4 is lost heart them in fact simultaneously.

At this moment,

pressure test device

10,20,30 and 40 each all send information to S40 with step S10, the information of this transmission comprises each pressure information that all loses heart of expression tire T1, T2, T3 and T4.That is, represent that the air pressure that loses heart of each tire T1, T2, T3 and T4 is not more than the standard atmosphere of 101kPa.

As shown in Figure 3, when the check ID that do not deposit, the definite result of control unit 54 in step S120 is ' denying ', make the processing of control unit 54 execution in step S150 in the step S210, thereby the detector ID of the detected air pressure of the actual standard atmosphere that is not more than 101kPa that receives simultaneously sequentially is temporarily stored in the memory device 55.

When the quantity of detector ID temporary in 60 seconds reached 4, this temporary detector ID formally was deposited with in this memory device 55 as check ID (seeing step S200 and S210).

Illustrate in passing, do not need to open in fact simultaneously the valve of tire T1, T2, T3 and T4.Make whole four tire T1, T2, T3 and T4 lose heart and be implemented within 60 that the quantity of temporary detector ID becomes 4 in memory device 55, while, execution in step S150 was to the processing of step S220 repeatedly, thereby formally deposited this temporary detector ID as check ID in memory device 55.

Whole four tire conditions of each other vehicle the situation that four tires all lose heart for example unlikely occurs under the situation of the normal control of this other vehicle in normal environment.

Therefore, might prevent that the detector ID of other vehicle tyre is deposited with the memory device 55 of own vehicle mistakenly according to the signal that sends from another vehicle detection device.

The tire of supposing at least one other vehicle is deflated, make the detector ID of flat of this at least one other vehicle receive and be temporarily stored in the memory device 55 by the control unit 54 of the vehicle V of oneself, then the temporary detector ID of this at least one other vehicle will handle cancellation in 60 seconds shown in the step S180 of control unit 54 and S220, because the tire of other maintenance at this at least one other vehicle does not lose heart, thereby prevented that the definite result in step S200 from being ' being '.

The result is in the first embodiment of the present invention, might prevent from the detector ID of other vehicle tyre to be deposited with mistakenly in the memory device 55 of own vehicle owing to the interference of other detector ID that sends from other vehicle.

In addition, in the first embodiment of the present invention, the structure of pneumatic pressure monitoring system of tire 1 makes this detector ID deposit and handles is to carry out in the tire pressure supervision treating process usually, and this will make that adding on-off element monitors that the control unit 54 of unit 50 forwards an ID to and deposits pattern to this tire pressure.And the structure of this pneumatic pressure monitoring system of tire 1 makes without any need for the device that is used to deposit detector ID (tool).

And, in the first embodiment of the present invention, the structure of pneumatic pressure monitoring system of tire 1 realizes carrying out ID and deposits to handle and need not tire pressure is monitored that the control unit 54 of unit 50 forwards ID to and deposits pattern, and this will make and might prevent that this tire pressure from monitoring that unit 50 carries out a normal running in supposition, for example is converted to an ID mistakenly in the state of vehicle V operation and deposits pattern.

In addition, in the first embodiment of the present invention, the structure of pneumatic pressure monitoring system of tire 1 makes this detector ID deposit processing and carries out in normal air pressure supervision treating process, even will making, this might deposit in the situation of processing beginning this ID, one of at least satisfying at tire T1 to T4 should be predetermined during alarm conditions, indicates an alarm exactly.

(second embodiment)

The second embodiment of the present invention is described subsequently.Explanation in passing, the program (program product) in the memory device 55 of being installed in a second embodiment is different from this program of first embodiment, and identical with hardware configuration in fact according to the hardware configuration of this pneumatic pressure monitoring system of tire of second embodiment according to the pneumatic pressure monitoring system of tire 1 of first embodiment, therefore according to the designated reference character identical of parts of the pneumatic pressure monitoring system of tire of this second embodiment with Fig. 1 parts.

In the pneumatic pressure monitoring system of tire of this second embodiment, this air pressure monitor unit 50 is carried out tire pressure supervision processing shown in Figure 4 according to ground program loop that is installed in the memory device 55.

That is, tire pressure monitors that the control unit 54 of unit 50 determines whether to receive each signal (step S310) with predetermined frequency band.

When determining not receive the signal with predetermined frequency band (when determining the result for ' deny ' in step S310), then tire pressure monitors that the control unit 54 of unit 50 stops these processes of execution, returns step S310.

On the other hand, when receive by antenna 52 and acceptor circuit 51 at least one send to control unit 54 have the signal of predetermined frequency band the time, this control unit 54 has determined to receive at least one signal (definite result of step S310 is ' being ') with this predetermined frequency band.

Subsequently, control unit 54 determines whether to have deposited check ID one of at least (step S320) in memory device 55, and when determining not deposit check ID in this memory device 55 (when the definite result among the step S320 is ' denying '), this control unit 54 forwards later step S330 to.

When determining that check ID one of at least is deposited with in this memory device 55 (the definite result among the step S320 is ' being '), whether this control unit 54 is read check ID one of at least from memory device 55, determine to be included in this detector ID of this received signal in one of at least and detect one of at least and have check ID one of at least (step S321).

Do not have this check ID one of at least the time when definite this detector ID checks out one of at least, promptly among the step S321 be defined as ' denying ' time, control unit 54 forwards later step S330 to.

When determine detector ID check out one of at least have check ID one of at least the time (the definite result among the step S321 is ' being '), this control unit 54 will determine to be included in the predetermined alarm conditions (step S322) whether detected air pressure in this received signal satisfies one of at least each tire.

When definite this detected air pressure one of at least satisfies should be predetermined during alarm conditions, in other words, when the definite result among the step S322 was ' denying ', control unit 54 forwarded later step S330 to.

Determining when control unit 54 that the air pressure that detect satisfy one of at least should be predetermined during alarm conditions (the definite result among the step S322 is ' being '), this control unit 54 is provided with this data, make indicating member 81 indicate alarms (step S324), thereby this indicating member 81 is provided with alarm of data indication according to this.

On the other hand, have this check ID one of at least the time (the definite result among the step S322 is ' denying ') when determining to be included in not checking out one of at least of this detector ID of received signal in one of at least, this control unit 54 determines to be included in the standard atmosphere (step S330) that whether is not more than one of at least 101 kPa of the detected air pressure of this received signal in one of at least.

When determining to be included in the standard atmosphere (the definite result among the step S330 is ' being ') that the detected air pressure of received signal in one of at least is not more than one of at least this 101 kPa, control unit 54 is temporary in this memory device 55 to be included in the detector ID of received signal in one of at least one of at least (step S340), and determines whether temporary detector ID number becomes 4 (step S350).

When determining that temporary detector ID number becomes 4 (the definite result in step S350 is ' being '), this control unit 54 is reset to zero (zero second) to the count value C1 that deposits timer TM1, so that make that depositing timer TM1 begins one and increase progressively counting (step S360).

On the other hand, when the quantity of determining temporary detector ID does not become 4 (the definite result among the step S350 is ' denying '), control unit 54 stops carrying out this processing and returns treatment step S310.

When determine to be included in the detected air pressure of received signal in one of at least one of at least greater than the standard atmosphere of 101kPa the time (the definite result in step S330 is ' deny '), whether this control unit 54 definite these count value C1 that deposit timer TM1 less than 5 minutes (step S370).

As the count value C1 that determines to deposit timer TM1 during less than 5 minutes (the definite result in step S370 is ' being '), whether this control unit 54 is determined to be included in the detector ID of received signal in one of at least and is checked out one of at least and have temporary detector ID one of at least (step S380).

Do not have temporary detector ID one of at least the time (the definite result in step S380 is ' deny ') when definite detector ID checks out one of at least, this control unit 54 stops carrying out this processing, returns the processing in step S310.

On the other hand, when determining that checking out one of at least of this detector ID has this temporary detector ID one of at least the time (the definite result among the step S380 is ' being '), this control unit 54 determines to be included in the standard atmosphere (step S390) of one of at least determining to be not less than 201 kPa of the detected air pressure of this received signal in one of at least.Pressure change from 101 kPa to 201 kPa is deposited condition corresponding to the sign this second embodiment.

When determining to be included in the detected air pressure of this received signal in one of at least one of at least less than the standard atmosphere of 201kPa (the definite result among the step S390 is ' deny '), this control unit 54 stops these treating processs of execution, so that return treatment step S310.

When determining to be included in the detected air pressure of received signal in one of at least and be not less than one of at least the standard atmosphere of this 201 kPa (the definite result among the step S390 is ' being '), control unit 54 is deposited one and is prepared sign and be set to corresponding to signal detected air pressure one of at least temporary detector ID one of at least one of at least (step S400).

Subsequently, control unit 54 determines whether temporary detector ID number becomes 4 (step S401), and when determining that this temporary detector ID number does not become 4 (the definite result in step S401 is ' denying '), this control unit 54 stops the execution of this processing, returns the processing among the step S310.

When determining that temporary detector ID number becomes 4 (the definite result among the step S401 is ' being '), these control unit 54 definite these are deposited the preparation sign and whether are set to whole four temporary detector ID (step S410).

When determining that this deposits (the definite result among the step S410 is ' deny ') when preparing sign and not being set to whole four temporary detector ID, control unit 54 stops these processing of execution and returns treatment step S310.

When determining that this deposits (the definite result among the step S410 is ' being ') when preparing sign and being set to whole four temporary detector ID, control is single formally to be deposited with (step S420) in the memory device 55 to detector ID as check ID.

On the other hand, when definite this count value C1 that deposits timer TM 1 is not less than 5 minutes (the definite result among the step S370 for ' deny '), this control unit 54 is cancelled the detector ID (step S430) that is temporarily stored in this memory device 55.

pressure test device

10,20,30 and 40 described according to second embodiment at this memory device 55.

At this moment,

pressure test device

10,20,30 and 40 each all send information to S40 with step S10, the information of this transmission comprises each pressure information that all loses heart of expression tire T1, T2, T3 and T4.That is, represent that the air pressure that loses heart of each tire T1, T2, T3 and T4 is not more than the standard atmosphere of 101 kPa.

As shown in Figure 4, when not depositing check ID, the definite result of control unit 54 in step S320 is ' denying ', and the definite result in step S330 is ' being ', because the air pressure that loses heart of each of expression tire T1, T2, T3 and T4 all is not more than the standard atmosphere of 101 kPa, make this control unit 54 execution in step S330 arrive the processing of step S350, thereby handle sequentially is temporarily stored in the memory device 55 with the detector ID that the detected air pressure that is not more than 101 kPa standard atmospheres receives simultaneously.

When temporary detector ID number reaches 4, when promptly all being temporarily stored in the memory device 55 corresponding to whole four detector ID of whole four pressure detection apparatuses of whole four tire T1, T2, T3 and T4, the count value C1 that deposits timer TM1 is reset to zero (zero second), so that start the counting of depositing timer TM1, shown in step S360.

On the other hand after whole four tire T1, T2, T3 and T4 exit, an extraction pipe preparing a compressor reducer and be communicated with it.

One of tire T1, T2, T3 and T4, for example the valve of tire T1 is communicated to the extraction pipe of compressor reducer, so that air is drawn into tire T1 from compressor reducer, thereby the air pressure among the tire T1 is increased to the preset air pressure of 201 kPa through 30 seconds.

This time, when because the air pressure among the tire T1 is 201 kPa and higher and this control unit 54 when receiving the air pressure of this tire T1 and the definite result among the step S330 for ' denying ', make control unit 54 execution in step S370 to the processing of step S410, thereby be arranged in this memory device 55 preparing sign corresponding to depositing of the pressure detection apparatus 10 of tire T1.

Subsequently, one of all the other tire T2, T3 and T4, for example tire T2 is communicated to the extraction pipe of compressor reducer, makes air from compressor reducer suction tire T2, thereby the air pressure among the tire T2 is increased to the preset air pressure of one 201 kPa within 30 seconds.

This time, when because the air pressure of tire T2 is 201 kPa and higher and control unit 54 when receiving the air pressure of wheel tires and the definite result in step S330 for ' denying ', make control unit 54 execution in step S370 to the processing of step S410, thereby be arranged in this memory device 55 preparing sign corresponding to depositing of the pressure detection apparatus 20 of tire T2.

Similarly, airbed is drawn in each of all the other tire T3 and T4, makes tire T3 and the T4 air pressure in each be increased to the preset air pressure of 201 kPa within 30 seconds and surpasses this preset air pressure.

Each the air pressure that receives this tire T3 and T4 at control unit 54 is so that carried out when the processing of step S370 in step S410 by this control unit 54, prepares sign corresponding to depositing of this pressure detection apparatus 30 of this tire T3 and T4 and 40 and sequentially is arranged in this memory device 55.

Then, because this compressor reducer has within 30 seconds the compressed capability that tire T1, T2, T3 and the T4 air pressure in each is increased to the set pressure of 201 kPa and surpasses this set pressure, so within 5 minutes, be enough to finish the operation that the air pressure of whole four tire T1, T2, T3 and the T4 that lose heart is increased to the set pressure of 201 kPa and surpasses this set pressure.

Therefore, after venting whole four tire T1, T2, T3 and T4, carry out the air pressure among whole four tire T1, T2, T3 and the T4 to be increased to and will to make and to deposit in vehicle assembling factory, agency etc. corresponding to the

pressure test device

10,20,30 of tire T1, T2, T3 and T4 and 40 detector ID above the operation of the set pressure of 201 kPa.

Whole four tire conditions of each other vehicle the situation that pressure change all appears in four tires for example unlikely occurs under the situation of the normal control of this other vehicle in normal environment.

In addition, the compressor reducer that has within 30 seconds the ability of the preset air pressure that the air pressure in the tire of common vehicle is increased to and surpasses 201 kPa is equipped on vehicle assembling factory, agency and other places.

The result is, in this second embodiment, anyly have the mistake of preventing and deposit under the component condition of function not adding, might prevent effectively because the interference of other detector ID that sends from other vehicle and the detector ID of other vehicle tyre being deposited with mistakenly in the memory device 55 of own vehicle V.

In addition, in the second embodiment of the present invention, the structure of pneumatic pressure monitoring system of tire 1 realizes that execution ID deposits processing and need not tire pressure is monitored that the control unit 54 of unit 50 forwards ID to and deposits pattern, this will make and might prevent that this tire pressure from monitoring that unit 50 in normal running of supposition execution, for example is converted to an ID mistakenly and deposits pattern in the state of vehicle V operation.

And, in the second embodiment of the present invention, the structure of pneumatic pressure monitoring system of tire 1 makes this detector ID deposit processing and carries out in normal air pressure supervision treating process, even will making, this might deposit in the situation of processing beginning this ID, one of at least satisfying at tire T1 to T4 should be predetermined during alarm conditions, indicates an alarm exactly.

17,27,37 and 47 sends once as impulse singla.

Because handling, each of above-mentioned controller 15B, 25B, 35B and 45B carried out once in per 60 seconds, so when the definite result in step S910 and S960 was ' denying ', shown in Figure 11 A, this impulse singla PA sent with 60 seconds interval.

By contrast, when the definite result in step S910 is ' denying ', and determine that in step S960 the result be ' being ', promptly each of detected air pressure is unusual when reducing, and shown in Figure 11 B, four impulse singlas of PB1 to PB4 are by every transmission in 15 seconds once.

And when the definite result in step S910 is ' being ', when promptly being set to ID and depositing pattern, shown in Figure 11 C, five impulse singlas of PC1 to PC5 send with 0.1 second interval.

Subsequently, with the processing and the operation that are used for depositing the detector ID of pressure test device 10B, 20B, 30B and 40B described according to the 4th embodiment at this memory device 55B.

At first, signal wire (SW) 63a, 63b, 63c and the 63d that is connected to device 60 is connected respectively to

antenna

16A, 26A, 36A and the 46A of this detecting device 10B, 20B, 30B and 40B.Energizing signal from device 60 is sent to

antenna

16A, 26A, 36A and 46A by signal wire (SW) 63a, 63b, 63c and 63d, makes this energizing signal send to controller 15B, 25B, 35B and 45B by T/

R circuit

17,27,37 and 47 respectively.

Shown in Figure 10 and 11, when each of controller 15B, 25B, 35B and 45B receives each of energizing signal, definite result of each controller 15B, 25B, 35B and 45B is ' being ' in step S910, so that each execution in step S920 of controller 15B, 25B, 35B and 45B to the processing of step S950, makes impulse singla (PC1, PC2, PC3, PC4 and PC5) monitor five times that unit 50B sequentially sends to this tire pressure with 0.1 second interval each from detecting device 10B, 20B, 30B and 40B.

Receive from impulse singla PC1, PC2, PC3, PC4 and the PC5 Be Controlled unit 54B of detecting device 10B, 20B, 30B, 40B and each transmission of 50B, and because the interval of this impulse singla is set to 0.1 second, so the definite result among the step S720 is ' being '.

At first, when for example impulse singla PC1 Be Controlled unit 55B that sends from for example detecting device 10B received, the definite result among this step S720 was ' being '.Owing to receive the count value C2 of intervalometer TM2 is zero, and the detector ID that does not deposit in memory device 55B, so the definite result among step S730 and the S790 is ' denying ', makes control unit 54B forward treatment step S820 to.

Owing to receive the count value C2 of intervalometer TM2 is zero, so the definite result among the step S820 is ' being ', and deposit the count value C1 of timer TM1 and the count value C2 of reception intervalometer TM2 and be reset, so that start the counting (seeing step S830) of depositing timer TM1 and this reception intervalometer TM2 respectively.

At that time, when control unit 54B received pulse signal, receive the impulse singla PC2 that sends from this detecting device 1 0B within 0.1 second after for example the previous impulse singla PC1 that sends from same detecting device 10B is received, the definite result in step S710, S720 and S730 is respectively ' being '.The result is that the processing among the execution in step S740 (is seen step S740) so that the detector ID of detecting device 10B is temporarily stored among the memory device 55B.

Unless whole four detector ID of whole four detecting device 10B, 20B, 30B and 40B are temporarily stored among the memory device 55B, the definite result in step S760 will be ' denying ', so that the processing of execution in step S710 to S760 repeatedly.

When carrying out above-mentioned treatment step S710 to S760, when the count value C1 that deposits timer TM1 is not less than 60 seconds (the definite result in step S750 is ' denying '), the detector ID that deletion is temporary makes that the processing of step S710 to S760 is carried out repeatedly.

Carry out the processing of above-mentioned steps S710 to S760, be not less than 60 seconds (the definite result among the step S750 is ' being ') up to the count value C1 that deposits timer TM1, within control unit 54B is receiving after each of the last impulse singla of each transmission of detecting device 20B, 30B and 40B 0.1 second from each of the detecting device 20B, the 30B that keep and 40B receive transmission impulse singla each the time, each of the definite result among step S710, S720 and the S730 is ' being '.The result is that the detector ID of detecting device 20B, 30B and 40B is temporarily stored in (referring to step S740) among the memory device 55B.

Because all whole detector ID of detecting device 10B, 20B, 30B and 40B are by temporary, till the count value C1 that deposits timer TM1 is not less than 60 seconds, so the definite result among the step S760 is ' being ', make this temporary detector ID formally be deposited with among this memory device 55B as check ID (referring to step S760).

On the other hand, when controller 15B, 25B, 35B and 45B did not receive each of energizing signal, shown in Figure 10 and 11, each definite result of controller 15B, 25B, 35B and 45B among the step S910 was ' denying '.

When each the detected air pressure of detecting device 10B, 20B, 30B and 40B reduces unusually (the definite result among the step S960 is ' being '), will be by treatment step S970, S980, S990 and the S950 in each execute exception transfer mode of controller 15B, 25B, 35B and 45B, make impulse singla (PB1, PB2, PB3 and PB4) monitor to tire pressure that unit 50B sequentially sent four times from each of detecting device 10B, 20B, 30B and 40B at interval with 15 seconds.

On the other hand, when each the detected air pressure of detecting device 10B, 20B, 30B and 40B is not reduced unusually (the definite result among the step S960 is ' denying '),, make impulse singla (PA) sequentially be sent to tire pressure from each of detecting device 10B, 20B, 30B and 40B and monitor unit 50B with the processing among cycle transfer mode execution in step S1000, S1010 and the S950 by each of controller 15B, 25B, 35B and 45B with 60 seconds intervening sequences ground.

Because interval between impulse singla PB1, PB2, PB3 and the PB4 in unusual transfer mode and the interval between the impulse singla PA in the cycle transfer mode are obviously greater than the interval between the impulse singla of depositing at ID in the pattern (PC1-PC5), so the definite result among the step S720 is ' denying ', so that processing of execution in step S790 to S830.

Promptly, detector ID is being deposited with among the memory device 55B as after checking ID, when receiving impulse singla PB1, PB2, PB3, PB4 and PA by control unit 54B one of at least the time, be included in received pulse signal PB1-PB4 and the PA detector ID in one of at least by with one of correspondence check ID examination.

When the detector ID of the impulse singla that is included in reception in one of at least checks out when having one of cooresponding check ID, definite result among the step S790 is ' being ', make when being included in the detected air pressure of received signal at least when satisfying one of at least the predetermined alarm status of each tire (the definite result among the step S800 is ' being '), these data will make alarm of indicating member 81 indications be set up, and make this indicating member 81 indicate an alarm.

As mentioned above, ID deposits and obviously is different from interval between impulse singla PB1, PB2, PB3 and the PB4 in the unusual transfer mode and the interval between the impulse singla PA in the cycle transfer mode between the impulse singla (PCI-PC5) in the pattern.

In the normal environment that comprises other vehicle normal operation; can not operate in the ID pattern of depositing for other vehicle comes the interval with 0.1 second to send five these impulse singlas; therefore; anyly have the mistake of preventing and deposit under the component condition that function takes place not adding, will avoid effectively because the caused detector ID the tire of another vehicle of interference of other detector ID that sends from other vehicle is deposited with the memory device 55B of vehicle V of oneself mistakenly.

In addition, because this device 60 is not connected to

antenna

16A, 26A, 36A and 46A when vehicle V normally moves, so in the fourth embodiment of the present invention, only receive under the situation of this energizing signal in each of controller 10B, 20B, 30B and 40B, each of controller 10B, 20B, 30B and 40B just operates in ID and deposits in the pattern, make that might carry out detector ID when vehicle V normally moves deposits processing, and this tire pressure is not monitored that the control unit 54B of unit 50B forwards ID mistakenly to and deposits pattern.

And, in the fourth embodiment of the present invention, the structure of pneumatic pressure monitoring system of tire 1B makes this detector ID deposit processing and carries out in normal air pressure supervision treating process, even will making, this might deposit in the situation of processing beginning this ID, one of at least satisfying at tire T1 to T4 should be predetermined during alarm conditions, indicates an alarm exactly.

Execution ID deposits operation when can be converted to the ID retained-mode in the operation mode of pneumatic pressure monitoring system of tire.
